TECHNICAL FIELD

The present disclosure relates to a cleaning tool capable of easilyattaching and detaching a web.

BACKGROUND

Various kinds of cleaning tools which are used by consumers exist.Examples of cleaning tools include sponges, mops, brooms, brushes, andthe like. In addition to such cleaning tools, many other products havebeen used for a long time. To satisfy various consumers' needs for easyuse, hygiene, reduction of the risk of injury to the user whilecleaning, and the like regarding such cleaning tools, research toimprove the cleaning tools has been consistently carried out from thepast to the present.

Meanwhile, cleaning tools have various forms and functions according toplaces and situations in which the cleaning tools are used. Among theseplaces and situations, in a place such as a bathroom where there is alot of moisture and thus pollutants, such as bacteria, fungi, and thelike, are frequently generated on wall surfaces, the pollutants may beremoved from the wall surfaces by applying a detergent to a surface of aweb, which can be made from, for example, a nonwoven fabric material,and rubbing the wall surfaces with the web. In recent years, adisposable toilet bowl scrubber (DTBS) web, which is manufactured torelease a detergent when brought into contact with moisture or damp airwithout the detergent being applied to a surface of a web, was alsoreleased into the market. When using such a web, a user should grip theweb while wearing rubber gloves on his or her hands, or should cleanusing a tool which enables the web to be attached thereto, and thereason for that is that, when a cleaning detergent applied to the webcomes into contact with the body of the user, the cleaning detergent mayadversely affect the skin of the user that comes into contact with thecleaning detergent.

A cleaning tool, which is configured to enable a web to be attachedthereto and to be used, generally includes a pipe type handle to enablea user to hold the cleaning tool with his or her hands, and is providedwith an attachment part to which a web is attachable at another portionof the cleaning tool except for the pipe type handle. Also, a web, whichis gripped at the cleaning tool, may be contaminated when used for along time, and thus the contaminated web should be replaced, and forthis purpose, the attachment part may be configured to enable the web tobe attached thereto and detached therefrom.

In a typical cleaning tool using a web, a user should hold a handle withone hand and seize a contaminated web with the other hand whenseparating the contaminated web from the typical cleaning tool toseparate the contaminated web therefrom. Consequently, there is aninconvenience in that the hands of the user are contaminated whileseparating the contaminated web or that the user should wear gloves toprevent the contamination of his or her hands.

Also, because the cleaning tool should be configured to include both thehandle and the attachment part configured to enable a web to be attachedthereto and detached therefrom, a structure of the cleaning tool issomewhat complicated and a manufacturing process thereof is notsimplified, causing manufacturing costs to become unnecessarilyexcessive and process time unnecessarily consumed during themanufacturing process.

DETAILED DESCRIPTION

Hereinafter, a concrete embodiment for implementing the spirit of thepresent disclosure will be described in detail with reference to theaccompanying drawings. Here, it should be noted that the drawings arenot constantly illustrated to scale for convenience of a description.Also, when a detailed description of related known configurations andfunctions is determined to obscure the gist of the present disclosure inthe following description of the present disclosure, the detaileddescription thereof will be omitted.

FIG. 1 is a perspective view illustrating an attachment of a web to acleaning tool according to one embodiment of the present disclosure.

Referring to FIG. 1, a cleaning tool 10 according to one embodiment ofthe present disclosure may be used in a state in which a web D isattached to the cleaning tool 10, and a user may rub the web D against aportion, such as a wall surface and the like, which requires cleaning sothat cleaning may be performed by a detergent which is applied to theweb D or released therefrom. For this purpose, the cleaning tool 10includes a body 100 having an attachment surface configured to enablethe web D to be attached thereto and detached therefrom, a handle 200configured to be grippable by the user, a pushing unit 300 configured toseparate the web D, which is attached to the attachment surface of thebody 100, from the attachment surface, and a rod 400 connected to thehandle 200 at an opposite side with respect to the body 100.

Here, the web D may be configured with a member made of a nonwovenfabric material, or with a foam including a sponge, a disposable toiletbowl scrubber (DTBS), and the like, and it may be used by a detergentbeing applied to a surface of the web D or may be manufactured in a formin which a solid detergent is coated on the surface thereof. Also, inthe case of the web D manufactured in a form in which the soliddetergent is coated on the surface of the web D, a cleaner ingredientmay be contained in the solid detergent, and such a cleaner ingredientmay be, for example, one among calcium carbonate, potassium carbonate,sodium carbonate, sodium bicarbonate, and sodium metasilicate. Such aweb D may be easily attached to the cleaning tool 10 by a hook 131,which will be described below, formed at the cleaning tool 10, and maybe easily separated from the cleaning tool 10 by a user simply pushingthe attached web D in a direction receding from the hook 131.

Hereinafter, a detailed configuration of such a cleaning tool 10 will bedescribed with reference to FIGS. 2 to 10. FIG. 2 is a perspective viewillustrating a separation of the web D and the rod 400 from the cleaningtool 10 of FIG. 1, FIG. 3 is a perspective view illustrating a shape ofthe attachment surface of the body 100 of FIG. 1, FIG. 4 is a lateralview illustrating a shape of the hook 131 of FIG. 3, FIG. 5 is aperspective view of a cross section of the handle 200 of FIG. 1, FIG. 6Ais a perspective view of an upper surface of a push bar of FIG. 1, FIG.6B is a perspective view of a lower surface of the push bar, FIG. 7 is adiagram illustrating a case in which the push bar of FIG. 1 is locatedat a first position, FIG. 8 is a diagram illustrating a case in whichthe push bar of FIG. 1 is located at a second position, FIG. 9 is adiagram illustrating a case in which the push bar of FIG. 1 is locatedat a third position, and FIG. 10 is a diagram for describing a procedurein which the web D gripped at the cleaning tool 10 of FIG. 1 isseparated therefrom by the pushing unit 300.

Referring to FIGS. 2 to 10, the body 100 may be configured in a plateshape having one surface and the other surface opposite thereto. Also, athrough-hole 110 communicating with an insertion depression 240 of thehandle 200, which will be described below, and enabling a push bar 320to pass through the through-hole 110 may be formed at a position of thebody 100 that corresponds to the insertion depression 240. Further, sucha through-hole 110 may be formed to face the insertion depression 240.For example, the body 100 and the handle 200 may be connected to eachother so that the insertion depression 240 of the handle 200 is locatedat a central portion of the body 100, and the through-hole 110 may beformed to pass through from the one surface to the other surface of thebody 100 at the central portion of the body 110. A pivot restrictionpart 111 may be formed around such a through-hole 110 to be selectivelyengageable with a push bar latch 322. Meanwhile, in the drawingsaccording to the present embodiment, the pivot restriction part 111 hasbeen illustrated in the form of a protrusion that protrudes from an edgeof the through-hole 110 and a recess formed at a central portion of theprotrusion, but the pivot restriction part 111 may be modified andimplemented in another form. For example, the edge of the through-hole110 may serve as the pivot restriction part 111, and alternatively, onlythe protrusion may be formed at the edge of the through-hole 110 toserve as the pivot restriction part 111.

A hinge fixing part 120 configured to fix a hinge 220 of the handle 200may be provided at the one surface of the body 100. Also, the attachmentsurface to and from which the web D is attached and detached is formedat a surface opposite that to which the handle 200 of the body 100 isconnected.

The attachment surface of the body 100 may include a hook existingregion 130 provided with the hook 131, which is provided to enable theweb D to be attached to the attachment surface, and a hook absent region140 not provided with the hook 131. The through-hole 110 may be formedat the center of the hook absent region 140, and the hook absent region140 may be formed to extend in one direction centering on such athrough-hole 110. The hook existing region 130 may be formed at bothsides of the hook absent region 140, and particularly, the hook existingregion 130 may be symmetrically formed centering on the hook absentregion 140. Also, the hook existing region 130 and the hook absentregion 140 may be provided to have a predetermined ratio of area, and,for example, they may be provided to have a ratio of 1:3. However, thespirit of the present disclosure is not limited thereto, and a ratio ofan area between the hook existing region 130 and the hook absent region140 may be freely modified and implemented without departing from thespirit of the present disclosure.

As is described above, the attachment surface may be divided into thehook existing region 130 and the hook absent region 140 so that aportion to which the web D is attached may be limited to some portion ofthe attachment surface. Consequently, the pushing unit 300 may be usedto facilitate the separation of the web D from the cleaning tool 10.Although a case in which the hook absent region 140 is provided at theattachment surface of the body 100 has been exemplified and described inthe present embodiment, in some cases, the attachment surface may bemodified and implemented so that the hook 131 is formed across theentirety of the attachment surface, and in this case, the separation ofthe web D may be somewhat difficult, and adhesion thereof may bestrengthened by as much as the separation of the web D is madedifficult.

Also, the hook 131 may have a shape such as a wedge, and, as oneexample, the hook 131 may be configured with a head portion 1311 and apillar portion 1312 connected thereto. At this point, the head portion1311 is configured with an upper surface having a rounded shape and alower surface which is connected to the pillar portion 1312 and has anarea that is greater than that of a jointed surface of the pillarportion 1312 so that the upper surface of the head portion 1311 may diginto a surface of the web D and then may be hooked to the surface togrip the web D. Also, an edge of the head portion 1311 is formed to havean appropriate area from the pillar portion 1312 rather than to have anexcessively wide area therefrom so that an excessive force may not berequired when separating the web D attached to the hook 131.

The handle 200 may be rotatably connected to the body 100. For example,the handle 200 may be configured to be pivoted in both directions withrespect to the body 100. Also, the handle 200 may include a column part210 extending in one direction and the hinge 220 configured to beconnected to the body 100. Such a hinge 220 may be provided at one endpart 201 of the handle 200, and may be diagonally disposed with respectto the one direction in which the column part 210 extends. For example,the hinge 220 and the column part 210 may be disposed to form an angleof 90 degrees therebetween, and particularly, they may be disposed toconfigure a “T” shape. The handle 200 may be pivoted and rotated throughsuch a hinge 220. Also, the rod 400 may be connected to the other endpart 202 of the handle 200.

An insert molding part 230 made of a rubber material may be formed atsome portion of a surface of the handle 200. As one example, the insertmolding part 230, which is made of a rubber material and is applied tothe handle 200, may be formed at a surface portion of the handle 200that is gripped with a hand of a user, and particularly, it may beformed at the other end part 202 of the handle 200. The hand of the usermay be prevented from sliding while cleaning by such an insert moldingpart 230 being made of a rubber material, and various colors andpatterns may be applied to a product due to a characteristic of aninsert molding technique to improve an aesthetic appearance of theproduct.

The insertion depression 240, into which the push bar 320 configuringthe pushing unit 300 is insertable, may be formed at the column part 210of the handle 200, and the insertion depression 240 may be formed to beconcave along a length direction of the column part 210. Such aninsertion depression 240 may be formed at a side of the handle 200,which is connected to the body 100. Also, a guide slot 250 may be formedto pass through an outward side of the column part 210 at acircumferential surface of the handle 200 to communicate with theinsertion depression 240. Such a guide slot 250 may be formed at thecolumn part 210 of the handle 200, and, similar to the insertiondepression 240, the guide slot 250 may be formed to be concave along thelength direction of the column part 210. Also, the guide slot 250 may beformed to have a width that is less than that of the insertiondepression 240. Such a guide slot 250 may guide a sliding guide 321which is formed at one surface of the push bar 320.

A first groove 270 may be formed in the insertion depression 240corresponding to an inner side surface of the handle 200. Such a firstgroove 270 may be engaged with a second groove 323 which is formed atthe push bar 320. Meanwhile, in the drawings according to the presentembodiment, the first groove 270 has been illustrated as being formed asa single protrusion, but the first groove 270 is not limited thereto andmay be freely modified and implemented in another form. For example, thefirst groove 270 may be formed as a plurality of recesses and the secondgroove 323 may be formed as a plurality of protrusions so that theplurality of recesses and the plurality of protrusions may berespectively engaged with each other.

The pushing unit 300 is configured to be movable along the handle 200and moves along a length direction of the handle 200 toward the outwardside thereof so that the web D may be separated from the attachmentsurface of the body 100. Also, the pushing unit 300 may include the pushbar 320 movably accommodated inside the handle 200 and a button 310provided to be manipulated by the hand of the user.

A plurality of grooves may be formed to be continuous at a surface ofthe button 310 in the form of a shape in which a ridge portion and avalley portion are repeated. This is for increasing a friction force toprevent fingers of the user from sliding by expanding an area cominginto contact with the fingers of the user when the user pushes thebutton 310. However, this is merely one example, and the shape of thebutton 310 may be freely modified and implemented without departing fromthe spirit of the present disclosure. Such a button 310 may be connectedto the push bar 320 through the sliding guide 321.

Such a sliding guide 321 may be formed to protrude from a centralportion of one surface of the push bar 320. The sliding guide 321 may beinserted into and guided by the guide slot 250 of the handle 200. As thesliding guide 321 moves inside the guide slot 250, movement of the pushbar 320 may be guided. Such a guide slot 250 is formed along the lengthdirection of the column part 210 so that the push bar 320 may also beguided along the length direction of the column part 210.

The push bar 320 may include a long member extending in one direction,and the push bar latch 322 may be formed at an end portion of such along member toward the body 100. As the push bar 320 moves toward theoutward side of the handle 200 along the length direction of the handle200, such a push bar latch 322 may be selectively engaged with the pivotrestriction part 111. Although the pivot restriction part 111 has beenillustrated as being formed as a protrusion and the push bar latch 322has been illustrated as being formed as a recess in the drawingsaccording to the present embodiment, the spirit of the presentdisclosure is not limited thereto. For example, the pivot restrictionpart 111 may be formed as a recess and the push bar latch 322 may beformed as a protrusion.

The push bar 320 may be selectively located at one position among afirst position at which the push bar 320 is maximally inserted into thehandle 200 and does not restrict the rotation of the handle 200 (See,FIG. 7), a second position at which the push bar 320 is slightly slidand moved toward the outward side of the handle 200 to such an extent asto enable the push bar latch 322 and the pivot restriction part 111 tobe engaged with each other (See, FIG. 8), and a third position at whichthe push bar 320 passes through the through-hole 110 to separate the webD from the body 100 (See, FIG. 9). Such a first position may be a statein which the push bar 320 is maximally pushed and inserted into theinsertion depression 240. In this case, the push bar latch 322 and thepivot restriction part 111 are spaced apart from each other so that therotation of the body 100 with respect to the handle 200 is notrestricted. When the push bar 320 is pushed toward the outward side ofthe handle 200 and thus is located at the second position in a state inwhich the handle 200 is inclined by a predetermined first angle a1 withrespect to the body 100, the rotation of the handle 200 may berestricted. Also, when the push bar 320 is pushed toward the outwardside of the handle 200 in a state in which the handle 200 is inclined bya predetermined second angle a2 with respect to the body 100, the pushbar 320 pushes the web D so that the web D may be separated from theattachment surface of the body 100. Each of the first angle a1 and thesecond angle a2 indicates an angle that does not exceed 90 degrees andis one angle among angles formed such that the handle 200 is inclinedwith respect to the body 100. Also, the first angle a1 may be formed tobe smaller than the second angle a2, and, for example, the first anglea1 may be 45 degrees and the second angle a2 may be 90 degrees.

One or more second grooves 323 may be formed in the push bar 320, andmay be engaged with the first groove 270 formed in the handle 200. As isdescribed above, the one or more second grooves 323 may be provided. Forexample, the second groove 323 may be configured with a first recess324, a second recess 325, and a third recess 326, and such first tothird recesses 324, 325, and 326 may be disposed in parallel with eachother along the length direction of the column part 210 from an outwardside of the push bar 320 toward an inward side thereof. In other words,such first to third recesses 324, 325, and 326 may be disposed along adirection that is the same as that in which the push bar 320 moves. Forexample, the third recess 326 may be formed to be disposed closest tothe other end part 202 of the handle 200, the first recess 324 may beformed to be disposed farthest away from the other end part 202 thereof,and the second recess 325 may be formed between the first recess 324 andthe third recess 326.

As is described above, when a plurality of second grooves 323 areformed, the first groove 270 may be selectively engaged with one amongthe first recess 324, the second recess 325, and the third recess 326.For example, the first recess 324 and a protrusion of the first groove270 may be engaged with each other when the push bar 320 is located atthe first position, the second recess 325 and the protrusion may beengaged with each other when the push bar 320 is located at the secondposition, and the third recess 326 and the protrusion may be engagedwith each other when the push bar 320 is located at the third position.

When the handle 200 is inclined by the predetermined first angle a1 withrespect to the body 100 and the second recess 325 and the protrusion ofthe first groove 270 are engaged with each other, the push bar latch 322and the pivot restriction part 111 are engaged with each other such thatthe rotation of the handle 200 may be restricted. Also, when the handle200 is inclined by the predetermined second angle a2 with respect to thebody 100 and the third recess 326 and the protrusion of the first groove270 are engaged with each other, the push bar 320 is pushed toward theoutward side of the handle 200 so that the web D may be separated fromthe attachment surface of the body 100 by the push bar 320.

Meanwhile, in the drawings according to the present embodiment, thesecond groove 323 has been illustrated as being configured with aplurality of recesses, but the second groove 323 is not limited theretoand may be freely modified and implemented in another form. For example,the second groove 323 may be configured with a single recess and thefirst groove 270 may be configured with a plurality of protrusions sothat the single recess may be selectively engaged with one among theplurality of protrusions.

The rod 400 may be selectively connected to the other end part 202 ofthe handle 200, which is an end part opposing one side of the handle 200connected to the body 100. For the purpose of such a connection, a clickprotrusion and a click depression may be respectively formed at the rod400 and the handle 200. For example, a click protrusion 410 may beformed at the rod 400, and a click depression 261 into which the clickprotrusion 410 is insertable may be formed at the handle 200. Also, arod connection depression 260, which is formed to be concave along thelength direction of the column part 210, may be formed at the other endpart 202 of the handle 200. When the handle 200 and the rod 400 areconnected to each other, a portion of the rod 400 at which the clickprotrusion 410 is formed is inserted into the rod connection depression260, and thus the click protrusion 410 may be engaged with the clickdepression 261. Also, such a rod connection depression 260 may beconfigured to communicate with the insertion depression 240. Such a rod400 may be used by being selectively coupled to the handle 200 accordingto convenience of the user. In other words, the user may use thecleaning tool 10 by gripping the handle 200 in a state in which the rod400 is separated from the handle 200 or by gripping the rod 400 in astate in which the rod 400 is coupled to the handle 200.

Hereinafter, an operation and an effect of the cleaning tool 10 havingthe above described configuration will be described.

A user may use the cleaning tool 10 by locating the push bar 320 at thefirst position or the second position and coupling the web D to theattachment surface of the body 100. Also, the user may clean whilefreely pivoting the handle 200 with respect to the body 100 by locatingthe push bar 320 at the first position, and may further clean in a statein which the pivoting of the handle 200 is restricted with respect tothe body 100 by locating the push bar 320 at the second position in astate in which the handle 200 is pivoted by a predetermined angle, andthus engaging the pivot restriction part 111 and the push bar latch 322with each other.

The user may selectively locate the push bar 320 at the first positionor the second position by moving the push bar 320 along the lengthdirection of the column part 210 using the button 310. For example, theuser may freely pivot and use the handle 200 by locating the push bar320 at the first position. Also, the user may use the cleaning tool 10in a state in which the pivoting of the handle 200 is restricted bypushing the push bar 320 toward the outward side of the handle 200 in astate in which the handle 200 is inclined by the predetermined firstangle a1 with respect to the body 100 and locating the push bar 320 atthe second position.

Meanwhile, since the web D becomes more and more contaminated ascleaning using the cleaning tool 10 is repeated, the contaminated web D,which is seriously contaminated and thus cannot be used for anymorecleaning, should be replaced. For this purpose, the web D should firstbe separated from the cleaning tool 10.

When separating the web D from the body 100, the user first locates thepush bar 320 at the first position to enable the handle 200 to be freelypivoted. Next, as shown in FIG. 10, the user pivots the handle 200 bythe second angle a2 and then pushes the push bar 320 toward the outwardside of the handle 200 using the button 310 to locate the push bar 320at the third position.
